G RAVITY-MOTOR.

SPECIFICATION forming part of Letters Patent No. 483,645, dated October 4, 1892.

Application led May 16, 1892. Serial No. 433,245. (No model.)

To @ZZ whom t may concern:

:Be it known that we, AMBnosn F. BRAKE and WILLIAM WONN, citizens of the United States of America, residing at Audubon, in the county of Audubon and State of Iowa, have invented a new and useful Gravity-Motor, of which the following is a specification.

Our object is to provide a motor specially adapted to be applied to a windmill-tower to supersede the use of a wind-wheel for operating a pump and other machinery.

Our invention consists in the construction, arrangement, and combination of mechanism for elevating and suspending a weight; mechanism for transmitting power from the weight to a train of loose gear-wheels on stationary shafts and to increase speed; auxiliary weights to add power and mechanism to govern power and motion and transmit it from the train of wheels and auxiliary weights; a system of levers for transmitting, increasing, and applying power to a pump or other machinery, and

an automatic stop device, as hereinafter set forth, pointed out in our claims, and illustrated in the accompanying drawings, in which- I Figure 1 is aside view of a portion of a tower, showing our invention applied and connected with a pump and a trough, as required in practical use for watering stock. Fig. 2 is a vertical sectional view on the line no Qc of Fig. l. Fig. 3 is a horizontal sectional view looking downward from the line y y in Fig. 1, clearly showing the connection of the governor Inechanism with the train of loose wheels. Fig. A is a sectional view showing a pin-wheel combined with a fixed shaft and the train of loose gearwheels. Fig. 5 is a detail View showing auxiliary weights combined with the pin-wheel and a system of levers for transmitting and uniting the power of the main weight and the power of the auxiliary weights. Fig. 6 is an end View of the drum by means of which the main weight is elevated and suspended, showing a lever and ratchet for rotating the drum and elevating the main weight therewith by means of a rope. Fig. 7 shows the other end of the drum and a pawl and ratchet for preventing a backward motion of the drum. Fig. 8 is a perspective view showing our complete invention in position as required for operating a pump to water stock.

A represents a tower or other suitable support for our mechanisms.

A2 is a frame adapted for mounting a drum and a train of gear-wheels thereon and'also adapted to be iixed to the tower A.

A3 is a drum iixed to a rotating shaft A4, mounted in bearings fixed to the frame A.

A5 is a lever pivotally connected with the shaft A4 and carries a spring-actuated pawl to engage a ratchet on the end of the drum, as shown in Fig. 6.

A6 is a rope or cable fixed to the drum A3 and extended over a pulley A7 at the top of gie tgwer to suspend a weight A8, as shown in A9 is a gear-wheel fixed to the end portion of the shaft A4.

B is a shaft fixed to the frame A in a plane above the shaft A4.

B2 is a gear-wheel loosely mounted on the shaft B.

B3 is a pinion or small wheel formed on or xed to the hub of the wheel B2 in such a manner that it will engage the wheel A9 on the shaft A4.

B4 is a gear-wheel corresponding in size with the wheel B2 and also mounted loosely on the shaft B, and B5 is a pinion or small wheel formed on or fixed to the hub of the wheel B4.

B6 is a collar fixed to the shaft B to retain tllefloose wheels in proper position upon the s a t. f

O is a shaft fixed to the frame A2 in a plane Y above the shaft B.

C2 is a gear-wheel mounted loosely on the shaft C and adapted in size and position to engage the small wheel B5 on the shaft B.

C3 is a small wheel formed on or fixed to the hub of the wheel C2 and adapted in size and position to engage the wheel B2 on the shaft B.

C4 is a duplex pin-wheel having a series of pins on each side, adapted to alternately e11- gage levers, as hereinafter described. It is loosely mounted on the shaft C, and C5 is a small geawwheel formed on or fixed to the hub thereof and adapted in size and location to engage the wheel B4 on the shaft B.

C6 and O7 are collars iixed to the shaft C by Ineans of set-screws to retain the loose wheels in proper positions relative to the wheels on the shaft B.

Nos. l and 2 are elbow-shaped levers pivoted to the lower end of a bearer D, that is fixed to the frame A2 in such a manner that IOO the short arms of the twol mating levers will alternately engage the pins on the opposite sides of the duplex pin-wheel C4, as required to be simultaneously vibrated thereby in opposite directions and to transmit power from the pin-wheel. On the long arm of each of the mating levers is an adjustable auxiliary weight D2 and D3, the force of which, as it moves like a pendulum, is united with the force transmitted from the main weight A8 through the rope and drum, the train of loose gear-wheels, and the duplex pin-wheel to the mating levers Nos. l and 2. .s

No. 3 is a lever pivoted to a branch F-o-f the bearer D and pivotally connected with the inner ends of the levers Nos. l and 2 by means of rods I-I and H2, that are pivoted to. the lever No. 3 at points equidistant from the fulcrum, as required to vibrate the lever in a vertical plane.

No. 4 is a lever fu-lcrumed to a suitable bearer on the tower A in a planev above the lever No. 3 to extend at right angles thereto to transmit power and motion from the lever Y No. 3 to a pump-rod J, as required to operate a pump K or other extraneous machinery that may be connected with the lever No. 4.

M is an L.-shaped device pivoted to the tower A and provided with a shoulder N at its upper end, adapted to engage the lever No. 4, as required, to retain the lever stationary. The lower end is connected with a rod P, that extends down into a watering-trough R and has a float S attached thereto in such a manner that theiioat will rise as the water rises in the trough to adjust the stop device M, so that it will engage the lever No. 4, as required, to arrest the motion of the machine and pump and prevent an overflow and waste of water from the trough.

In the practical operation of our invention the main weight AB is readily elevated by manually operating the lever A5 to actuate the drum A3 to wind the rope A6 thereon. The gravity-power of the weight will then be applied to rotate the drum and shaft A4 and the wheel A9, fixed to the shaft A4, jointly, as required, to transmit power and motion to the wheels Ba and B2 on the fixed shaft B,- from said wheels to the wheels C3 and C2 on the fixed shaft C, from the wheel C2 to the joint wheels B5 and B4 on the shaft B, and from the wheel B4 tothe wheel C5 and duplex pin-wheel jointly mounted upon the shaft C. The power thus transmitted to and concentrated in the duplex pin-wheel from the main weight and the motionof said pin-wheel, increased by the train of Vloose gear-wheels, is next transmitted and augmented by means of the levers Nos. l and 2 and the auxiliary weights suspended thereon to the lever No. 3, by the alternate motions of said mating levers Nos. l and 2 as they are alternately engaged by the pins of the pin-wheel to be alternately vibrated thereby, and the rotary motion of the pin-wheel thereby converted into a reciprocating vibratcry motion, and the joint action of the two mating levers is transmitted to the lever No. 3, to the lever No. 4, and from` thence to the pump-rod or such other extraneous machin ery as may be connected therewith.

It is obvious that the pin-wheel as connected with the train of loose wheels and the levers Nos. l and 2 also performs the functions of an escapement in releasing and utilizing the power stored in the drum by means of the rope wou nd thereon and the weight suspended from the end of the rope. It is also obvious that the auxiliary weights adjustably connected with the long arms of thesmating Ylevers Nos. l and 2 serve as a means of governing the speed of the train of .wheelsand the motion of the levers that intervene between the wheels and the pump or other extraneous machinery connected with the lever N o. 4, as required to regulate the operation of such machinery. Elevating the auxiliary weights increases speed and lowering them diminishes it.

We claim as our inventionl. In a gravity-motor, a drum-wheel fixed to a rotating shaft, a rope xed to the drum and extended over a pulley supported in a higher plane, and a weight attached to the free end of the rope, a fixed shaft extended parallel with the rotating shaft, a gear-wheel having a smaller wheel on its hub mounted loosely on the fixed shaft extended parallel with the first-mentioned fixed shaft, and a gear-wheel mounted loosely thereon to engage the small wheel on the first fixed shaft and small wheel onY the hub thereof Yto engage the large wheel on the rst shaft, and a duplex pin-wheel mounted loosely on the second fixed shaft, and a small gear-wheel combined with the hub of the pin-wheel to engage one of the larger wheels on the first fixed shaft, arranged and combined to operate in the manner set forth, for the purposes stated.

2. In a gravity-motor, two uniform elbowshaped levers pivoted at the central portions of their short arms and in parallel position to vibrate in vertical planes and a weight adj ustably attached to the lower end of thelong arm of each of said mating levers, and the free end of each short arm adapted to engage the pins of a pin-wheel, in combination with a duplex rotating pin-wheel, to operate in the manner set forth, for the purposes stated.
